Synchrotrons SPring

Isothermal crystallization was observed by means of SAXS and a polarizing optical microscope (POM, OLYMPUS, BX or BHS-751-P). The SAXS experiment was carried out using synchrotron radiation on the beam line BL40B2 of SPringS (SP8) at JASRI in Harima and at the BL-10C small angle installation of the Photon Factory (PF) at KEK in Tsukuba.

Microbeam X-ray diffraction with beam sizes in the micrometer range is a useful and powerful method to investigate the in situ transition of the crystalline region and the local structure for monofilaments. To reveal the detailed fiber structure and the distribution of the two types of molecular conformations (a- and P-structure crystals) in monofilaments, microbeam X-ray diffraction was performed using synchrotron radiation at SPring-8, Japan. The beam size was focused to 0.5 pm with a Fresnel zone plate (Suzuki et al. 2001) and the monofilament was linearly scanned perpendicularly to the fiber axis with a step of 2 pm.
